A fuel pump is used when the fuel tank is mounted lower than the carburetor and cannot use gravity to carry fuel through the fuel line. Briggs & Stratton fuel pumps develop pressure using the vacuum in the crankcase, which is created by the motion of the piston. A fitting on the crankcase cover or the dipstick tube draws the pressure to pump fuel
Note - While this is a genuine manufacturer's part for Briggs & Stratton engines, it fits a ton of other engine manufacturers too and is the most common fuel pump used on Craftsman, Toro, Husqvarna lawn tractors
